DKY4A Distributor swop?

[JonE]

John, I went through lots of lists and discovered a later Lucas 60s unit which ran the same way and bought a couple of new old stock units on the basis of wanting something reliable for the longer term. I have a Reliant manifold and was going to explore using the vacuum facility too, as said manifold (like a cast Ruby unit but with downdraft) is plumbed for it.
That said, would it not be better finding a decent DK4A to get yours back to original spec?
